Pinpoint Test 12: The Front Control Interface Module (Fcim) Does Not Respond to the Scan Tool
PINPOINT TEST 12: THE FRONT CONTROL INTERFACE MODULE (FCIM) DOES NOT RESPOND TO THE SCAN TOOLNormal Operation
The front control interface module (FCIM) communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits (GY/O) (MS-CAN +) and (V/O) (MS-CAN -) provide the network connection to the FCIM. The FCIM shares the MS-CAN network with the instrument cluster, electronic manual temperature control (EMTC) module, smart junction box (SJB), audio unit, front display interface module (FDIM) and satellite radio receiver. Voltage to the FCIM is provided by circuit (BR/R). Ground is provided by circuit (B/L).
Possible Causes
- Fuse
- Wiring, terminals or connectors
- FCIM
Diagnostic Procedure
CAUTION:lure to use the correct probe adapter(s) may damage the connector.
